Dear All,
Mine is Fedora Core 6 :
eth0 ( Internet )
eth1 ( Intranet )
Now, due to the envoriment problem, the eth1 need to be disable at
this moment, so I try to do the following config
[root@host1 ~]$ cat /etc/sysconfig/network-scripts/ifcfg-eth1
# Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+
DEVICE=eth1
BROADCAST=192.168.1.255
# HWADDR=00:17:31:7E:F8:34
IPADDR=192.168.1.254
# IPV6ADDR=
# IPV6PREFIX=
NETMASK=255.255.255.0
NETWORK=192.168.1.0
# ONBOOT=yes
ONBOOT=no
[root@host1 ~]$
After reboot the network function, the server machine can't to
connect with Internet again :
[root@host1 ~]$ ping -c 3 202.175.xxx.xxx
PING 202.175.xxx.xxx (202.175.xxx.xxx) 56(84) bytes of data.
From 202.175.xxx.xxx icmp_seq=1 Destination Host Unreachable
From 202.175.xxx.xxx icmp_seq=2 Destination Host Unreachable
From 202.175.xxx.xxx icmp_seq=3 Destination Host Unreachable
So, how must I modify the config of eth1 interface, then the
connection of Internet will be successful ?
Uncomment the "HWADDR=" line to ensure that the configuration ties to
the correct NIC. It's possible that the ifcfg-eth1 setup is really
messing with eth0 instead.
Second, make sure the default gateway is set up correctly, as your
problem sounds like it's not being set. If your default gateway is
on the network served by the ifcfg-eth1 file above, then it won't be
set as you don't have a NIC on that network. The default gateway is set
by a "GATEWAY=" line in one of the ifcfg-eth* files or in the
/etc/sysconfig/network file.
It'd help if you could post the contents of the following files:
/etc/sysconfig/network-scripts/ifcfg-eth0
/etc/sysconfig/network-scripts/ifcfg-eth1
/etc/sysconfig/network
Also the output of the commands "ifcfg eth0" and "ifcfg eth1". You can
obfuscate the actual network addresses if you wish or send the stuff to
me off-list and I can try to help you directly.

Hello,
[root@host1 ~]$ cat /etc/sysconfig/network-scripts/ifcfg-eth0
# VIA Technologies, Inc. VT6102 [Rhine-II]
DEVICE=eth0
BROADCAST=202.175.xxx.xxx
# HWADDR=00:0D:0B:A7:9A:7B
IPADDR=202.175.xxx.xxx
# IPV6ADDR=
# IPV6PREFIX=
NETMASK=255.255.255.248
NETWORK=202.175.xxx.xxx
ONBOOT=yes
[root@host1 ~]$
[root@host1 ~]$ cat /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=yes
HOSTNAME=host1
GATEWAY=202.175.xxx.xxx
[root@host1 ~]$
So, would you mind to give me more suggestion / idea / solution ?
Ok, I don't see anything grotesquely wrong with that so far although
I can't verify the default gateway is on eth0's network. You defined
a /29 network for it but only gave me the /16 addresses.
Try bringing it up again and run "ifcfg eth0" to verify that it indeed
has an IP address on the 202.175.*.* network. If it does, then do a
"netstat -rn" and verify you have a default route (denoted by a "G"
under the "FLAGS" column). If you don't see that, then the gateway
you've defined isn't on eth0's network and we need to look more closely
at your network settings.
